Regarding the quality I didn't mean to say that ffmpeg couldn't match the quality of ffmpeg2theora with the correct settings, just the settings that I used for my trials which was only -qscale 10. I left ffmpeg2theora on the default setting which I read was 6 if I'm not mistaken. Anyways, regardless of adjustments I had roughly the same speed everytime that's what I meant when I said I didn't see any significant changes.
Yes this (theora) wouldn't be something I would want to use everyday, I was just doing some testing and noticed that it's quite slow no matter what I did and I came here to make sure it wasn't something wrong I was doing. :-) So seems it's not me but the nature of the codec. I appreciate the help everyone.
